Gardening expert Benedict Vanheems has urged gardeners to sow five specific seeds this March to ensure a bountiful summer harvest. Vanheems, who runs the Grow Veg YouTube channel, warns that delaying planting could lead to regret when summer arrives.
Tomatoes top the list, with Vanheems recommending sowing them six to eight weeks before the final frost. He advises using all-purpose compost in a pot, spacing seeds half an inch apart, and placing the pot on a heatmat to encourage germination. Once seedlings develop, they can be transferred to individual pots before being planted outdoors after the last frost.
Potatoes are also best planted in March, according to Vanheems. He suggests waiting for seed potatoes to sprout before planting them in a large pot in a greenhouse to protect them from frost. This method, he says, provides a head start on the harvest.
Peas, onions, and kohlrabi round out the list. Vanheems recommends sowing hardy peas in plug trays to protect them from pests, planting onion sets now for a timely harvest, and trying kohlrabi, a vegetable he describes as resembling 'a baby alien head'.
